Circular has introduced two new smart rings, the Ring 3 Pro and Ring 3 Slim, at IFA 2026. Both models track activity, sleep, blood oxygen and heart rate variability, while also adding a vibration motor for silent alarms and other alerts.
The Ring 3 Pro offers more advanced features, including FDA-cleared ECG functionality, blood-pressure monitoring and a larger battery. Both rings also support contactless NFC payments with compatible Visa and Mastercard cards, a feature still missing from many competing smart rings.
Circular’s Kira app uses AI to provide personalized health insights and recommendations based on the collected data. Pricing and availability have not yet been announced.
